Hi Anjali,
Your Group Discussion ppt is okay. It needs to have some examples or visuals, and try putting some more data. But your Body Language ppt does not speak clear language and sounds too jazzy without getting to the point. You need to work on this ppt. It should have images of correct and incorrect body language. Always remember pictures have a great impact that data and catch the eye of your listener, helping them to become engrossed. Also, the bullets that you have used are a bit confusing. Try using simple bullets, concentrate on specific data, and give more weightage to body posture pictures.
